I could not recover a single file so there is no Pros in my case
I have PAID almost $100 and wasn't able to open any file. For each file deleted in the past the software showed thousands of results but my computer was not able to open any one of them. Wasted money and time.
Since I could not recover a single file, for me downloading the paid version of this software was a waste of money and time. In the end, another free software made a better job recovering my shift-deleted Excel spreadsheet.
